Application filed March 81, 1903 Serial No. 150,8 70. (No model.)

To all whom/it may concern:

Be it known that we,WILLIAM EOOLES, residing at Heworth, York, and JOHNLORAINE ROBSON, residing at Bishopthorpe road,York, England, subjects ofthe King of Great Britain, have invented certain new and usefulImprovements in Windows, of which the following is a specification, suchas will enable thoseskilled in the art to which it appertains to makeand use the same.

The object of this invention is to provide an improvement in windowswhereby counterbalanced sashes may be conveniently swung or turned intoa room, so as to facilitate the cleaning thereof; and with these andother objects in view the invention consists in the construction,combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in'the following specificatiom'of whichthe accompanying drawings form a part, in which the separate parts ofour improvement are designated by suitable reference characters in eachof the views, and in which-- Figure 1 is a front view of a Window-frameprovided with the usual sashes and embodying our invention, the sashesbeing shown in an open position; Fig. 2, a cross-sectionon the line 2 2of Fig. 1; Fig. 3, a view similar to Fig. 2, but showing a modified formand the sashes closed; Fig. 4., a detail view showing means forsupporting the counterbalanceweights when it is desired to disconnectthe cords from the sashes at one side, so as to swing the-sashesinwardly; Fig. 5, a detail of a device for connecting thecounterbalance-cords with the sashes, and Fig. 6 a view of anotherdetail of the construction.

Our improvement, which can be fixed to any existing sashes, consists ofmetal tubes A and D, fixed in the place of the present front and centralbeads or strips at one side of window-frame and revoluble on suitablesupports at the top and bottom thereof and forming a hinge or hingesupon which the sashes open into a room. In these tubes are formedvertical slots or openings A and the sashes are provided with plates B,located at proper intervals and provided with knobs or heads 13*,movable in said tubes and connected with the plates B'by necks B movablein the slots A and by means of this construction the sashes are free tobe moved up and down in the usual manner when closed, and when thesashes are open the knobs or heads B hold them in the manner of a hinge.

On the side of the window-frame opposite the tubes A is a safeguard J,comprising a handle portion J a plate J and shank J which passes throughan opening J in a front face-plate secured to the window-frame andthrough the middle separating-partition L and so located as to be abouttwo inches under the counterbalance-weights J when the sashes are drawndown to the bottom of the window-frame, and this safeguard supports theweight to allow the cords at that side to be detached from thewindow-sashes when it is desired to open the sashes for any pnrpose.

The center bead or strip G at the side of the window-frame opposite thetubes A is also formed of separate parts hinged together, as shown at Gso that said head or strip may be folded upwardly high enough to allowthe sashes when in their lowermost position to be swung inwardly, andwhen the parts of this bead or strip are in their normal position theymay be secured in any desired manner.

The front head or strip II on the side of the frame opposite the tube Ais hinged to the frame, so that it may be swung inwardly and turned backinto place whenever desired in order that the sashes may be swunginwardly, as shown in Figs. 1 and 2, and when this head or strip is inits normal position it may also be secured in any desired manner.

The counterbalance-cords N are provided with spring-hook-attachingdevices F, having forked shanks F between which the counterbalance-cordsare secured by means of screws F, the heads of which are countersunk, asshown at F, and this construction allows new cords to be substitutedwhenever necessary, and the sashes are provided at their opposite sideswith any suitable devices with which the hooks F may engage.

The bottom sash is designated. by the reference character N and the topsash by the reference character N and these sashes are provided with theusual grooves N in which the counterbalance-cords are free to move.\Vhen the sashes are of'unusual weight, clips K are provided and securedto parts of the window-frame, as shown in Fig. 3, and engage the tubesA, so .as to strengthen the same, and these clips are preferably fixedslightly above the middle portions of said tubes or at any desired pointthereon.

The separate parts of this apparatus may be made of any desiredmaterial, brass or other suitable metal being preferred, and can bepainted the same as the rest of the frame or sashes and will not appearat all unsightly, and in practice the tube A is preferably slightlycountersunk in the adjacent side or part of the frame, as shown in Fig.2. The slots A in the tubes A and D are enlarged at their upper ends, asshown at A to permit of the knobs or heads 13 being passed into saidtubes, and ateach end of these tubes a plate 0 is secured to thewindow-frame and provided with trunnions G which enter. the ends of saidtubes and form pivots or hinges on which the said tubes are free toturn, and these plates 0 may be secured to the bottom and top of thewindow-frame or to the side thereof, as may be desired, and the plates Cmay be any desired shape or form, according to the shape or form of thewindow-frame. It will be understood that the opposite sides of the frameare provided with the usual vertically-arranged spaces in which theweights J and the counterbalance cords and weights operate in the samemanner as with other apparatus of this class.

Having fully described our invention, what We claim as new, and desireto secure by Letters Patent, is

1. A window-frame provided at one side with tubes which take the placeof the central and front bead or strip and which are rotatablysupported, said tubes being provided rsaezs provided with knobs or headsadapted to be inserted into said tubes and having necks movable in saidslots, said sashes being provided with counterbalance Weights and cords,substantially as shown and described.

3. A window-frame provided at one side with tubes which take the placeof the central and front bead or strip and which are rotatablysupported, said tubes being provided in one side with a vertical slot,and sashes provided with knobs or heads adapted to be inserted into saidtubes and having necks movable in said slots, said sashes being providedwith counterbalance weights and cords, and the frame being provided atone side with means for supporting the counterbalanceweights when it isdesired to detach the cords thereof from the sashes, substantially asshown and described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of the subscribing witnesses, this 17th day ofMarch, 1903.
